[0002]
[Prior art]
Hereinafter, two examples of a conventional vehicle door check device will be described.
[0003]
The vehicle door check device 100 shown in FIG. 9 is a so-called shoe type, and includes a door check case Assy unit 102 arranged with the vertical direction of the door as a longitudinal direction, and the door check case Assy unit 102. A long check arm 104 arranged with the direction orthogonal to the longitudinal direction as a longitudinal direction is a main part.
[0004]
The door check case Assy unit 102 fixed to the door hinge side of the side door is configured by a box-shaped case 106 and a flat-plate-shaped base 108 fitted on the case 106. Rectangular openings 110 and 112 are formed at intermediate portions in the longitudinal direction of the case 106 and the base 108. An insertion space is formed between the openings 110 and 112, and the check arm 104 is inserted through the insertion space.
[0005]
A pair of upper and lower shoes 114 are accommodated in an internal space formed by the case 106 and the base 108. The shoes 114 are substantially H-shaped when viewed from the front, and are pressed and urged toward each other by the elastic restoring force of the cube-shaped cushion rubber 116.
[0006]
On the other hand, the check arm 104 is formed in a long shape, and a circular hole 118 penetrating in the vertical direction is formed at one end 104A in the longitudinal direction. The check arm 104 is connected to the mounting bracket on the body side through the circular hole 118 so as to be relatively rotatable. A rectangular block-shaped stopper 120 is set at the other end 104B in the longitudinal direction of the check arm 104 to prevent the check arm 104 from coming off the door check case assembly part 102.
[0007]
Further, check patterns 122 constituting a sliding surface of the shoe 114 of the door check case assembly part 102 are respectively formed on the upper and lower surfaces of the middle part of the check arm 104 in the longitudinal direction. The check pattern 122 will be described in more detail. A first raised portion 124 having a low protruding height is formed near the one end 104A of the check arm 104, and the protruding height is close to the other end 104B of the check arm 104. A second raised portion 126 having a high height is formed. The first raised portion 124 is set on the first gentle slope 124A set on the one end 104A side, the first convex surface 124B that is substantially parallel to the general surface of the check arm 104, and the other end 104B side. The second gentle slope 124C. On the other hand, the second raised portion 126 includes a first steep slope 126A set on the one end portion 104A side, a second convex surface 126B that is substantially parallel to the general surface of the check arm 104, and the other end portion 104B side. The second steep slope 126C is set.
[0008]
As a disclosure example of the vehicle door check device belonging to the shoe type described above, there is Japanese Utility Model Publication No. 57-109160.
[0009]
According to the above configuration, when the side door is opened and closed, the pair of shoes 114 slide on the check pattern 122 formed on the upper and lower surfaces of the check arm 104 accordingly. At this time, the sliding resistance gradually increases when the shoe 114 rises on the first gentle slope 124A of the first raised portion 124, and is constant when the shoe 114 slides on the first convex surface 124B. When a high sliding resistance is generated and the shoe 114 descends on the second gentle slope 124C, the sliding resistance gradually decreases. When the shoe 114 slides on the second raised portion 126, basically the same change in sliding resistance as when sliding on the first raised portion 124 is observed. Since the bulging portion 124 and the second bulging portion 126 have different inclination angles, the sliding resistance increases and decreases when sliding on the second bulging portion 126. The increase or decrease in the sliding resistance appears as an operation load at the time of opening / closing the side door, and as an operation feeling at the time of opening / closing the door.
[0010]
On the other hand, the vehicle door check device 130 shown in FIG. 10 is a so-called roller type, and a pair of shoes 138 are provided in a case 134 and a base 136 that constitute an outer shape of the door check case Assy unit 132. Is housed. The shoe 138 is pressed and urged by the compression coil spring 140, and a roller 142 is held at the tip of the shoe 138. That is, instead of the configuration in which the shoe 114 is pressed by the cushion rubber 116 described above, the shoe 138 having the roller 142 held at the tip is pressed and urged by the urging force of the compression coil spring 140. Since other configurations are the same as those of the shoe type vehicle door check device 100 described above, the same reference numerals are given and description thereof is omitted. The operation is the same as that of the shoe type vehicle door check device 100 described above.
[0011]
[Problems to be solved by the invention]
By the way, an operation load characteristic is required to smoothly open the side door when the door is opened, whereas an operation load characteristic is required to securely close the side door when the door is closed. That is, conflicting operation load characteristics are required when the door is open and when the door is closed.
[0012]
On the other hand, in the two conventional vehicle door check devices 100 and 130 described above, only one type of check pattern 122 for determining the door opening / closing operation load and thus the door opening / closing operation feeling is set. Accordingly, the check pattern 122 is set by selecting one of the operation load characteristic when the door is opened and the operation load characteristic when the door is closed. This means that the operation load characteristic that is not selected is abandoned.
[0013]
In view of the above facts, an object of the present invention is to provide a vehicle door check device that can obtain good operation load characteristics and operation feeling both when the door is opened and when the door is closed.
[0014]
  According to the first aspect of the present invention, there is provided a long check arm in which one end side in the longitudinal direction is connected to the vehicle body side so as to be relatively rotatable, and a check pattern including a plurality of concave and convex surfaces is formed in an intermediate part in the longitudinal direction. And a door check case Assy portion provided with a moving body that is provided on the door hinge side of the vehicle door and increases or decreases the door opening / closing operation load by tracing the check pattern of the check arm as the door is opened and closed. In the vehicle door check device, a first check pattern for opening the door and a second check pattern for closing the door exhibiting different operation load characteristics are provided in the middle portion in the longitudinal direction of the check arm. ButSide by sideHas beenIn addition, the first check pattern and the second check pattern are connected to each other at three switching surfaces corresponding to each of the time when the door is fully open, when the door is half open, and when the door is fully closed.,Further, the first check pattern shows an operation load characteristic in which the operation load becomes low when the vehicle door starts to be opened, and the second check pattern has a low operation load when the vehicle door starts to be closed and ends the closing. Shows the operating load characteristics that can provide assisting force to fully close the vehicle door when approaching.It is characterized by that.
[0016]
  Claim 2The vehicle door check device according to the present invention as described,Claim 1In the invention according to claim 1, the switching of the moving body from the first check pattern to the second check pattern and the switching of the moving body from the second check pattern to the first check pattern are performed when a door is opened and closed. It is made using the movement to the opposite direction which acts on case Assy part and a check arm, It is characterized by the above-mentioned.
[0017]
  Claim 3The vehicle door check device according to the present invention is described in claim 1.Or claim 2In the invention described in item 1, the moving body includes a ball that rolls on a check pattern.
[0018]
According to the first aspect of the present invention, when the door opening / closing operation of the vehicle door is performed, the moving body included in the door check case Assy portion is formed in the middle portion in the longitudinal direction of the check arm. Trace up. The check pattern includes a plurality of uneven surfaces, and the door opening / closing operation load is increased or decreased by tracing the plurality of uneven surfaces by the moving body.
[0019]
  Here, in the present invention, two types of the check patterns are set. That is, in the present invention, there are two types of the check arm, the first check pattern that the moving body traces when the door is opened and the second check pattern that the moving body traces when the door is closed, in the middle portion in the longitudinal direction of the check arm. The check pattern is set. In addition, the first check pattern and the second check pattern exhibit different operation load characteristics. Therefore, the operation load characteristic required when the door is opened can be realized by the first check pattern, and the operation load characteristic required when the door is closed can be realized by the second check pattern.
  Specifically, in the present invention, the first check pattern shows an operation load characteristic that the operation load becomes low when the vehicle door starts to be opened, and the second check pattern shows that when the vehicle door starts to close. The operation load characteristic is such that an assisting force for fully closing the vehicle door is obtained when the operation load is low and approaches the end of closing.
[0020]
  Also,According to the present invention, the first check pattern and the second check pattern described above are arranged side by side, and the two check patterns are provided on three switching surfaces corresponding to each of the time when the door is fully open, when the door is half open, and when the door is fully closed. For example, when the vehicle door is fully opened after being fully opened, the moving body moves from the corresponding switching surface to the first check pattern side when the door is fully closed, and the first check is performed. After tracing the pattern, it moves to the second check pattern side at the corresponding switching surface when the door is fully opened, and traces the second check pattern to return to the original position.
[0021]
As described above, in the present invention, the first check pattern for opening the door and the second check pattern for closing the door are arranged side by side, and both correspond to each time when the door is fully open, when the door is half open, and when the door is fully closed. Since the three switching surfaces are connected to each other, it is possible to avoid an increase in the size of the check arm, particularly in the width direction.
[0022]
  Claim 2According to the described invention, the switching of the moving body from the first check pattern to the second check pattern and the switching from the second check pattern to the first check pattern performed on the three switching surfaces described above are performed by the door. This is performed by utilizing the movements in opposite directions that act on the door check case assembly part and the check arm when opening and closing. Specifically, when the door is open, the door check case Assy portion provided on the door hinge side of the vehicle door moves to the outside of the passenger compartment, whereas the check arm tries to stay at that position. When viewed from the check case assembly side, the check arm is relatively swung toward the vehicle interior side. On the other hand, when the door is closed, the door check case Assy portion moves toward the vehicle interior side, whereas the check arm tries to stay in that position, so when viewed from the door check case Assy portion side, Is swung relatively to the outside of the passenger compartment. This is the same in the conventional vehicle door check device. In the present invention, however, the relative movement is used to switch between the first check pattern and the second check pattern of the moving body. It is what you want to do. For this reason, it is possible to switch between the first check pattern and the second check pattern of the moving body without adding any special configuration.
[0023]
  Claim 3According to the described invention, since the moving body described above includes a ball that rolls on the check pattern, smooth movement of the moving body can be ensured. In particular, in relation to the inventions of claim 2 and claim 3, the moving body needs to move in a direction crossing between the first check pattern and the second check pattern arranged side by side. Since it can also roll in the direction, the interchanging operation can be performed very smoothly.
[0024]

In addition, in the internal space formed by the case 16 and the base 18, a pair of upper and lower compression coil springs 30 (“biasing means” including a resin component that can be elastically deformed in a broad sense) corresponding to each shoe 26. Is grasped). One end of the compression coil spring 30 is abutted and locked to the upper inner surface or the lower inner surface of the case 16, and the other end of the compression coil spring 30 is abutted and locked to the back surface of the cradle 26 </ b> B of the shoe 26. Has been. Therefore, as shown in FIG. 4, the pair of compression coil springs 30 press and urge the pair of shoes 26 and the check ball 28 toward each other.
[0030]
FIG. 5 is a schematic cross-sectional view of the side door 32 as a “vehicle door”. As shown in this figure, the door check case Assy portion 14 constituting one of the vehicle door check devices 10 described above is fixed to the inner side surface of the front end portion of the door inner panel 34 of the side door 32. Specifically, by screwing a nut (not shown) into the fixing bolt 22 protruding from the case 16, the door check case Assy unit 14 is moved to the inner side surface (more precisely, the door inner) of the door inner panel 34. It is fixed to a hinge side panel disposed on the front end side of the panel 34 or a check reinforcement attached to the hinge side panel.
[0031]
On the other hand, as shown in FIG. 1 and the like, the check arm 12 is formed in an elongated shape, and a circular hole 36 penetrating in the vertical direction is formed in one end portion 12A in the longitudinal direction. The check arm 12 is connected to the body side mounting bracket 38 (see FIG. 5) corresponding to the circular hole 36 of the one end 12A so as to be relatively rotatable by a fixing means such as a fixing pin (not shown). The arm rotation center line P (see FIG. 1), which is the axis of the fixing means, passes in the vicinity of the door hinge center Q (see FIG. 5) of the side door 32.
[0032]
The longitudinal intermediate portion 12B of the check arm 12 passes through the opening 20 of the case 16 and the opening 24 of the base 18 of the door check case assembly portion 14 as described above, and the other end of the check arm 12 in the longitudinal direction. The part 12 </ b> C protrudes outside the base 18. A rectangular block-like stopper 40 is set at the other end portion 12C, and serves to prevent the check arm 12 from coming off the door check case assembly portion 14. Further, as will be described later, the check arm 12 needs to be relatively displaced with respect to the door check case assembly 14 by being swung in the vehicle interior side direction and the vehicle interior outside direction with respect to the door check case assembly portion 14. In order to ensure a deflection width (stroke), the width direction dimension of the check arm 12 is set to be smaller than the opening widths of the opening 20 of the case 16 and the opening 24 of the base 18.
[0033]
Further, check patterns 42 constituting the raceway surface of the check ball 28 of the door check case assembly 14 are formed on the upper and lower surfaces of the intermediate portion in the longitudinal direction of the check arm 12 described above. The check pattern 42 includes a first check pattern 44 disposed on the outer side of the vehicle interior and a second check pattern 46 disposed on the vehicle interior side, both of which are arranged in parallel in the width direction of the check arm 12. . Since the first check pattern 44 and the second check pattern 46 have different concavo-convex relationships, a predetermined step (height difference) is formed between them (see FIG. 6).
[0034]
The check pattern 42 will be described in more detail. In the first check pattern 44, a first raised portion 48 having a low protruding height is formed closer to the one end portion 12A, and a protruding height closer to the other end portion 12C. A second raised portion 50 having a high height is formed. The first raised portion 48 is set on the first gentle slope 48A set on the one end 12A side, the first convex surface 48B that forms a surface substantially parallel to the general surface of the check arm 12, and the other end 12C side. The first steep slope 48C. Similarly, the second raised portion 50 includes a second gentle slope 50A set on the one end 12A side, a second convex surface 50B located at a position higher than the first convex surface, and a second convex surface set on the other end 12C side. 2 steep slopes 50C. The slopes of the first gentle slope 48A and the second gentle slope 50A are long, and the slopes of the first steep slope 48C and the second steep slope 50C are short.
[0035]
Moreover, in the 2nd check pattern 46, the 3rd protruding part 52 with a low protrusion height is formed in the direction close | similar to the other end part 12C, and the 4th protrusion part with a high protrusion height is near the one end part 12A. 54 is formed. The third raised portion 52 is set on the third gentle slope 52A set on the other end 12C side, the third convex surface 52B that forms a surface substantially parallel to the general surface of the check arm 12, and the one end 12A side. And the third steep slope 52C. Similarly, the 4th protruding part 54 was set to the 4th gentle slope 54A set to the other end part 12C side, the 4th convex surface 54B in a position higher than the 3rd convex surface 52B, and the one end part 12A side. And a fourth steep slope 54C. The slopes of the third gentle slope 52A and the fourth gentle slope 54A are long, and the slopes of the third steep slope 52C and the fourth steep slope 54C are short.
[0036]
Further supplementing the first to fourth raised portions 48 to 54, the first raised portion 48 and the third raised portion 52, and the second raised portion 50 and the fourth raised portion 54 have the same shape. Each has a point-symmetrical positional relationship.
[0037]
In addition, the first check pattern 44 and the second check pattern 46 described above include a concave (dented) first switching surface 56, a second switching surface 58, and a third switching that are set at three locations. The surfaces 60 are connected to each other. The first switching surface 56 is set at a position adjacent to the first raised portion 48 and the fourth raised portion 54 (on the one end portion 12A side of the check arm 12), and the second switching surface 58 is set to the first raised portion 48. And the fourth raised portion 54 and the second raised portion 50 and the third raised portion 52, and the third switching surface 60 is positioned adjacent to the second raised portion 50 and the third raised portion 52 ( The other end 12C side of the check arm 12) is set.
[0038]
In the above configuration, the shoe 26, the check ball 28, and the compression coil spring 30 correspond to the “moving body” in the present invention.
[0039]
Next, the operation and effect of this embodiment will be described.
[0040]
First, the opening / closing operation of the side door 32 and the movement of the door check case assembly part 14 and the check arm 12 associated therewith will be described.
[0041]
As shown in FIG. 3, when the side door 32 is opened, the door check case Assy portion 14 fixed to the side door 32 is located outside the passenger compartment around the arm rotation center line P (in the direction of arrow A in FIG. 3). It is turned to. At this time, since the check arm 12 tries to keep the state as it is, when viewed from the door check case Assy unit 14, the check arm 12 is relatively swung toward the vehicle interior side (the direction of the arrow C in the figure). Will be.
[0042]
On the contrary, when the side door 32 is closed, the door check case Assy unit 14 fixed to the side door 32 is turned around the arm rotation center line P toward the vehicle interior side (the arrow B direction side in the figure). At this time, since the check arm 12 tries to keep the state as it is, when this is viewed from the door check case Assy unit 14, the check arm 12 is relatively swung to the outside of the passenger compartment (in the direction of arrow D in the figure). Will be.
[0043]
Summarizing the correlation between the door opening / closing operation and the movement of each part, when the side door 32 is opened, the door check case assembly 14 turns to the outside of the passenger compartment and the check arm 12 is swung to the inner side of the passenger compartment. On the other hand, when the side door 32 is closed, the door check case assembly part 14 turns to the vehicle interior side, and the check arm 12 is swung to the vehicle interior outside. That is, the door check case assembly 14 and the check arm 12 try to move in directions opposite to each other.
[0044]
Next, how the check ball 28 rolls on the check pattern 42 according to the door opening / closing operation based on the relative movement will be described.
[0045]
FIG. 7 shows where the check ball 28 is on the check pattern 42 in accordance with the door opening / closing operation. As shown in this figure, when the side door 32 is in the fully closed state, the check ball 28 of the door check case Assy unit 14 is positioned on the first switching surface 56. When the side door 32 is opened from this state, the check arm 12 is swung toward the vehicle interior side according to the relative movement described above. For this reason, the check ball 28 enters the first gentle slope 48A of the first raised portion 48 of the first check pattern 44 set outside the passenger compartment, and moves on the first raised portion 48 in the direction of arrow E in FIG. It moves up and down while rolling and reaches the second switching surface 58 corresponding to the door half-open state. Thereafter, when the side door 32 is further opened from the door half-open state, the check ball 28 moves up and down while rolling on the second raised portion 50 of the first check pattern 44, and the third switching corresponding to the door fully open state is performed. A plane 60 is reached.
[0046]
Looking at the door operation load characteristic when the door is opened, the characteristic is as shown by the graph X in FIG. That is, when the side door 32 starts to be opened, the check ball 28 rolls on the first gentle slope 48A having the long first raised portion 48, so that the operation load is relatively low. A low operating load means that the side door 32 can be opened smoothly. Therefore, according to this embodiment, when the door is opened, the side door 32 can be opened smoothly, and a good operation feeling can be obtained.
[0047]
Note that, after the one cushion is placed in the half-opened state of the door, the check ball 28 rolls on the second raised portion 50, so that the operation load becomes somewhat high, and the occupant is notified that the side door 32 is fully opened.
[0048]
On the other hand, when closing the side door 32 in the fully open state, the check arm 12 is swung to the outside of the passenger compartment according to the relative movement described above. For this reason, the check ball 28 held on the third switching surface 60 enters the third gentle slope 52A of the third raised portion 52 of the second check pattern 46 set on the vehicle interior side, and the third raised 7 moves up and down while rolling in the direction of arrow F in FIG. 7 to reach the second switching surface 58 corresponding to the door half-open state. Thereafter, when the side door 32 is further closed from the door half open state, the check ball 28 moves up and down while rolling on the fourth raised portion 54 of the second check pattern 46, and the first cut corresponding to the door fully closed state. The replacement surface 56 is reached.
[0049]
Looking at the door operation load characteristic when the door is closed, the characteristic is as shown in the graph Y of FIG. That is, when the side door 32 starts to close, the check ball 28 rolls on the third gentle slope 52A of the third raised portion 52, so that the operation load is relatively low, and the operation of starting the closing smoothly is performed. It can be carried out. Then, as the end of closing the side door 32 is approached, the check ball 28 rolls on the fourth steep slope 54 </ b> C of the fourth raised portion 54 at an accelerated speed, so that the side door 32 can be closed vigorously. In other words, the assisting force when the occupant fully closes the side door 32 can be obtained by the check ball 28 descending on the steep fourth steep slope 54C. Therefore, according to the present embodiment, the side door 32 can be firmly closed when the door is closed, and a good operation feeling can be obtained. In particular, a problem that the side door 32 is difficult to close in a vehicle having a large side door 32 in spite of a narrow interior space has been pointed out conventionally, but according to the present embodiment, the side door 32 of such a vehicle is not provided. There is also an advantage that the difficulty of closing can be reduced.
[0050]
When the side door 32 is temporarily opened from the fully closed state to the fully closed state again, the check ball 28 climbs over the first raised portion 48 of the first check pattern 44 and enters the second switching surface. After reaching 58, the vehicle goes over the fourth raised portion 54 of the second check pattern 46 and returns to the first switching surface 56.
[0051]
As described above, in the present embodiment, the check arm 12 that determines the operation load characteristic at the time of opening and closing the door has two types of check patterns that are tuned so as to show the optimum operation load characteristic (that is, the door opening time characteristic). Since the first check pattern 44 and the second check pattern 46 for closing the door are set, it is possible to obtain a good operation load characteristic and an operation feeling both when the door is open and when the door is closed.
[0052]
Further, in the present embodiment, the first check pattern 44 and the second check pattern 46 are arranged side by side in the middle portion of the check arm 12 in the longitudinal direction, and both are opened when the door is fully closed, when the door is half open, and when the door is fully opened. Since the first switching surface 56, the second switching surface 58, and the third switching surface 60 corresponding to each of the check arms 12 are connected to each other, it is possible to avoid an increase in the size of the check arm 12 particularly in the width direction. . As a result, according to the present embodiment, the compact check arm 12 can provide good operation load characteristics when opening and closing the door, and thus an operation feeling.
[0053]
Further, in the present embodiment, the first switching surface 56 to the third switching surface 60 are used by utilizing movements in opposite directions that act on the door check case assembly 14 and the check arm 12 when the door is opened and closed. The check ball 28 is switched (transferred) from the first check pattern 44 to the second check pattern 46 and switched from the second check pattern 46 to the first check pattern 44 (transfer). Even without adding a special configuration, switching (transfer) between the first check pattern 44 and the second check pattern 46 of the check ball 28 can be performed. As a result, according to the present embodiment, the structure of the vehicle door check device 10 is not complicated.
[0054]
In the present embodiment, the check ball 28 is held by the pair of shoes 26 and the check ball 28 is configured to roll on the check pattern 42. Therefore, the smooth movement of the shoe 26 can be ensured. .
